Organic or sulfhydryl containing (e.g., mercaptan, hydrogen sulfide, etc.):
(under subclass 119) Subject matter in which (1) an organic sulfur containing specie or (2) a specie containing the -Sh radical is sought by qualitative or quantitative chemical analysis.
(1) Note. The sulfhydry radical is -SH and thus includes mercaptans and thiois, and hydrosulfides.
(2) Note. See subclass 133 for a definition of organic.
(3) Note. This subclass provides for hydrogen sulfide and mercaptan tests. These tests are also referred to as sulfhydryl or hydrosulfide test.
